# kubectl config
|
|
|
|
> Manage Kubernetes configuration (kubeconfig) files for accessing clusters via `kubectl` or the Kubernetes API.
|
|
> By default, the Kubernetes will get its configuration from `${HOME}/.kube/config`.
|
|
> See also: `kubectx`, `kubens`.
|
|
> More information: <https://kubernetes.io/docs/reference/kubectl/generated/kubectl_config>.

|
- Get all contexts in the default kubeconfig file:
|
|
|
|
`kubectl config get-contexts`
|
|
|
|
- Get all clusters/contexts/users in a custom kubeconfig file:
|
|
|
|
`kubectl config {{get-clusters|get-contexts|get-users}} --kubeconfig {{path/to/kubeconfig.yaml}}`
|
|
|
|
- Get the current context:
|
|
|
|
`kubectl config current-context`
|
|
|
|
- Set the default namespace of the current context:
|
|
|
|
`kubectl config set-context --current --namespace {{namespace}}`
|
|
|
|
- Switch to another context:
|
|
|
|
`kubectl config {{use|use-context}} {{context_name}}`
|
|
|
|
- Delete clusters/contexts/users:
|
|
|
|
`kubectl config {{delete-cluster|delete-context|delete-user}} {{cluster|context|user}}`
|
|
|
|
- Permanently add custom kubeconfig files:
|
|
|
|
`export KUBECONFIG="{{$HOME.kube/config:path/to/custom_kubeconfig.yaml}}" kubectl config get-contexts`
